Sheet ABS plastic (abs)
The number of layers of the sheet by co-extrusion varies from one to five. The use of two or more layers in the leaves, obtained by coextrusion, allows you to combine the properties of different types improving their properties. For example, manufactured by coextrusion plastic ABS/PMMA combines decorative properties of acrylic and such properties plastic, mechanical strength and processability.
Special properties of the sheet by the customer are provided by the introduction of special additives during extrusion. Thus can be obtained:
- fire resistant plastic that does not support combustion beyond the source of open flame;
- plastic, resistant to UV radiation for the articles exposed to outdoor sunlight;
- frost-resistant plastic with reduced brittleness for products used at very low ambient temperatures.
ABS has high impact strength and wear resistance, non-toxicity and elasticity. Mostly the material used for the manufacture of products by thermoforming. Easily withstands atmospheric conditions and the temperature difference. Operating temperature from -50°C to +80°C. Resistant to alkalis, lubricating oils, solutions of inorganic salts and acids, hydrocarbons, oils, gasoline.
In the automotive industry on the basis of ABS plastic and its compositions are the details of the interior and exterior of the car. This includes panels, frames, plates, instrument panels, window frames, door trim and other interior parts, grille, wheel caps, body lights and exterior mirrors, the neck of the collector, door trim, bumper. Relatively widespread use in the automotive industry found a composition based on ABS plastic – ABS / PC.
Used in the manufacture of parts of refrigerators, televisions, vending equipment, tuning cars, the ABS plastic used in other areas, such as: advertising, consumer goods, building industry, medicine and others.
Features ABS (akrilnitrilbutadienstirol)
Sheets made of ABS — plastic combine high impact strength, good resistance to weathering, made way monolayer or multilayer extrusion. ABS sheets may have either a smooth or an embossed surface, a variety of colors and shades (including opaque). Available UV — stabilization of the sheet.

The above values relate to the thermoplastic immediately after extrusion and does not take into account the impact of aging.
resistant to water and aqueous salt solutions, dilute acids and alkalis, saturated hydrocarbons, vegetable and animal oils and fats; not resistant to aromatic hydrocarbons, chlorinated hydrocarbons, concentrated mineral acids, strong oxidizers
it has high hardness, is resistant to temperature changes, extremely resistant to atmospheric conditions
usually ABS withstand short-term heating to 90-100°C, heat resistant up to 110-130°C. The maximum permanent operating temperature: 75-80°C
flammable exposed to a flame or when approaching an appropriate amount of heat; brightly lit and unstable after removal of the flame with a strong formation of soot; spontaneous combustion at 350°C, fire from an external source at 450°C
IN ELECTRIC PROPERTIES
high electrical, high dielectric losses
- pneumatic vacuum forming
- printability, varnish
- hot knurling
these materials can be used for the production of thermoformed parts both internal and exterior of automobiles, buses, tractors, agricultural machinery, etc. (panels, covers, roof, fenders, bumpers, spoilers, side skirts, etc.), cases, luggage, furniture, internal parts of refrigerators, sanitary equipment, decoration, suspended ceilings, finishing bathrooms, outdoor advertising products, and so on. d.
